Chemical Compound
A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound. A compound can be transformed into a different substance by a chemical reaction, which may involve interactions with other substances. In this process, bonds between atoms may be broken and/or new bonds formed. There are four major types of compounds, distinguished by how the constituent atoms are bonded together. Molecular compounds are held together by covalent bonds; ionic compounds are held together by ionic bonds; intermetallic compounds are held together by metallic bonds; coordination complexes are held together by coordinate covalent bonds. Non-stoichiometric compounds form a disputed marginal case. A chemical formula specifies the number of atoms of each element in a compound molecule, using the s ...

Henry VII Of England
Henry VII (28 January 1457 – 21 April 1509) was King of England and Lord of Ireland from his seizure of the crown on 22 August 1485 until his death in 1509. He was the first monarch of the House of Tudor. Henry's mother, Margaret Beaufort, was a descendant of the Lancastrian branch of the House of Plantagenet. Henry's father, Edmund Tudor, 1st Earl of Richmond, a half-brother of Henry VI of England and a member of the Welsh Tudors of Penmynydd, died three months before his son Henry was born. During Henry's early years, his uncle Henry VI was fighting against Edward IV, a member of the Yorkist Plantagenet branch. After Edward retook the throne in 1471, Henry Tudor spent 14 years in exile in Brittany. He attained the throne when his forces, supported by France, Scotland, and Wales, defeated Edward IV's brother Richard III at the Battle of Bosworth Field, the culmination of the Wars of the Roses. He was the last king of England to win his throne on the field of battle. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry VIII Of England
Henry VIII (28 June 149128 January 1547) was King of England from 22 April 1509 until his death in 1547. Henry is best known for his six marriages, and for his efforts to have his first marriage (to Catherine of Aragon) annulled. His disagreement with Pope Clement VII about such an annulment led Henry to initiate the English Reformation, separating the Church of England from papal authority. He appointed himself Supreme Head of the Church of England and dissolved convents and monasteries, for which he was excommunicated by the pope. Henry is also known as "the father of the Royal Navy" as he invested heavily in the navy and increased its size from a few to more than 50 ships, and established the Navy Board. Domestically, Henry is known for his radical changes to the English Constitution, ushering in the theory of the divine right of kings in opposition to papal supremacy. He also greatly expanded royal power during his reign. He frequently used charges of treason and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Excommunication
Excommunication is an institutional act of religious censure used to end or at least regulate the communion of a member of a congregation with other members of the religious institution who are in normal communion with each other. The purpose of the institutional act is to deprive, suspend, or limit membership in a religious community or to restrict certain rights within it, in particular, those of being in communion with other members of the congregation, and of receiving the sacraments. It is practiced by all of the ancient churches (such as the Catholic Church, Oriental Orthodox churches and the Eastern Orthodox churches) as well as by other Christian denominations, but it is also used more generally to refer to similar types of institutional religious exclusionary practices and shunning among other religious groups. The Amish have also been known to excommunicate members that were either seen or known for breaking rules, or questioning the church, a practice known as shun ...

Wool
Wool is the textile fibre obtained from sheep and other mammals, especially goats, rabbits, and camelids. The term may also refer to inorganic materials, such as mineral wool and glass wool, that have properties similar to animal wool. As an animal fibre, wool consists of protein together with a small percentage of lipids. This makes it chemically quite distinct from cotton and other plant fibres, which are mainly cellulose. Characteristics Wool is produced by follicles which are small cells located in the skin. These follicles are located in the upper layer of the skin called the epidermis and push down into the second skin layer called the dermis as the wool fibers grow. Follicles can be classed as either primary or secondary follicles. Primary follicles produce three types of fiber: kemp, medullated fibers, and true wool fibers. Secondary follicles only produce true wool fibers. Medullated fibers share nearly identical characteristics to hair and are long but lack c ...

Mordant
A mordant or dye fixative is a substance used to set (i.e. bind) dyes on fabrics by forming a coordination complex with the dye, which then attaches to the fabric (or tissue). It may be used for dyeing fabrics or for intensifying stains in biological specimen, cell or tissue preparations. Although mordants are still used, especially by small batch dyers, it has been largely displaced in industry by substantive dye, directs.} The term mordant comes from the Latin ''mordere'', "to bite". In the past, it was thought that a mordant helped the dye bite onto the fiber so that it would hold fast during washing. A mordant is often a polyvalency (chemistry), polyvalent metal ion, and one example is chromium (III). The resulting coordination complex of dye and ion is colloidal and can be either acidic or base (chemistry), alkaline. Common dye mordants Mordants include tannic acid, oxalic acid, alum, chrome alum, sodium chloride, and certain salt (chemistry), salts of aluminium, chrom ...

Papal States
The Papal States ( ; it, Stato Pontificio, ), officially the State of the Church ( it, Stato della Chiesa, ; la, Status Ecclesiasticus;), were a series of territories in the Italian Peninsula under the direct sovereign rule of the pope from 756 until 1870. They were among the major states of Italy from the 8th century until the unification of Italy, between 1859 and 1870. The state had its origins in the rise of Christianity throughout Italy, and with it the rising influence of the Christian Church. By the mid-8th century, with the decline of the Byzantine Empire in Italy, the Papacy became effectively sovereign. Several Christian rulers, including the Frankish kings Charlemagne and Pepin the Short, further donated lands to be governed by the Church. During the Renaissance, the papal territory expanded greatly and the pope became one of Italy's most important secular rulers as well as the head of the Church. At their zenith, the Papal States covered most of the modern Ital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle East
The Middle East ( ar, الشرق الأوسط, ISO 233: ) is a geopolitical region commonly encompassing Arabian Peninsula, Arabia (including the Arabian Peninsula and Bahrain), Anatolia, Asia Minor (Asian part of Turkey except Hatay Province), East Thrace (European part of Turkey), Egypt, Iran, the Levant (including Syria (region), Ash-Shām and Cyprus), Mesopotamia (modern-day Iraq), and the Socotra Governorate, Socotra Archipelago (a part of Yemen). The term came into widespread usage as a replacement of the term Near East (as opposed to the Far East) beginning in the early 20th century. The term "Middle East" has led to some confusion over its changing definitions, and has been viewed by some to be discriminatory or too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of Western Asia (including Iran), but without the South Caucasus, and additionally includes all of Egypt (not just the Sina ...

Traditional Chinese Medicine
Traditional Chinese medicine (TCM) is an alternative medical practice drawn from traditional medicine in China. It has been described as "fraught with pseudoscience", with the majority of its treatments having no logical mechanism of action. Medicine in traditional China encompassed a range of sometimes competing health and healing practices, folk beliefs, literati theory and Confucian philosophy, herbal remedies, food, diet, exercise, medical specializations, and schools of thought. In the early twentieth century, Chinese cultural and political modernizers worked to eliminate traditional practices as backward and unscientific. Traditional practitioners then selected elements of philosophy and practice and organized them into what they called "Chinese medicine" (''Zhongyi''). In the 1950s, the Chinese government sponsored the integration of Chinese and Western medicine, and in the Great Proletarian Cultural Revolution of the 1960s, promoted Chinese medicine as inexpensive a ...

Ayurveda
Ayurveda () is an alternative medicine system with historical roots in the Indian subcontinent. The theory and practice of Ayurveda is pseudoscientific. Ayurveda is heavily practiced in India and Nepal, where around 80% of the population report using it. Ayurveda therapies have varied and evolved over more than two millennia. Therapies include herbal medicines, special diets, meditation, yoga, massage, laxatives, enemas, and medical oils. Ayurvedic preparations are typically based on complex herbal compounds, minerals, and metal substances (perhaps under the influence of early Indian alchemy or ''rasashastra''). Ancient Ayurveda texts also taught surgical techniques, including rhinoplasty, kidney stone extractions, sutures, and the extraction of foreign objects. The main classical Ayurveda texts begin with accounts of the transmission of medical knowledge from the gods to sages, and then to human physicians.
